object variable as follows: Dim Mail As MailSender Create an instance of the AspEmail object as follows: Set Mail = New MailSender ASP.NET AspEmail comes with an ASP.NET wrapper assembly, ASPEMAILLib.dll, which has to be placed in the \Bin subdirectory of your ASP.NET application. Alternatively, you can place this file in the Global Assembly Cache. In C#, create an instance of AspEmail as follows: <%@ Import Namespace="ASPEMAILLib" %> 2.2 Essential Properties and Methods In order to send email, AspEmail "talks" to an SMTP server. The SMTP server does not have to be running on the same machine as AspEmail, in fact it can be located anywhere on the local network or the Internet. You must specify the address of your SMTP server via the Host property. The default port number for SMTP services is 25, but if your SMTP server runs on a different port, you must also specify it via the Port property: Mail.Host = "smtp.mycompany.com" ' Required Mail.Port = 25 ' Optional. Port is 25 by default You may also specify a comma- or semicolon-separated list of SMTP hosts, as follows: Mail.Host = "smtp.domain1.com;smtp2.domain1.com;host.domain2.com" If the first host on the list is down, AspEmail will automatically attempt to connect to the second host, etc. If none of the specified hosts are working, an error exception will be thrown. You must also specify the sender's email address and, optionally, name as follows: Mail.From = "sales@mycompany.com" ' Required Mail.FromName = "Sales Department" ' Optional To add message recipients, CCs, BCCs, and Reply-To's, use the AddAd

Other Stuff How To Use On http://www.powerasp.net/content/new/on-error-resume-next.asp Error Resume Next Often when using ASP or Active Server Pages with VBScript you will find it necessary to check for errors when you do certain things that may fail and then handle http://p2p.wrox.com/asp-pro-code-clinic/9830-cdo-email-errors-not-trapped-error.html it accordingly. Things like opening a database connection or writing to a text file come to mind. Generally if an error is encountered in your .asp file, the processing of your script stops and error handling an error message is returned to the browser.
